Hoping to get free contact lenses, Freddy goes to the optician. (F=Freddy; O=optician)
F : Could you help me check my eyes, please?
O : Sure. Please have a seat and put on these glasses.Now, tell me. Which letters seem clearer?
F : The ones on the right.
O : OK. Can you read these price tags?
F : Yes. They're as clear as daylight.
O : Fine. Read out the highest amount.
F : US$100.
O : Right. That's what it'll cost you.
F : But I thought the contact lenses are free.
O : Yes. But you'll have to pay for our service.
F : No wonder they say, "There's no such thing as a free lunch."
